1.The initial state for brick may be defined by more than one block.
2.If Nb_integr > 1, the optional continuation lines have to be repeated for each integration point, if Keyword2 = STRS_F and 8-node solid element with 1 or 8 integration point.

3.If Nb_integr > 1, the optional continuation lines have to be repeated for each integration point, if Keyword2 = STRS_FGLO and 16-node or 20-node solid elements, 8-node HA8 elements, 8-node HSEPH elements, 6-node PA6 elements; 8-node HSEPH elements, 6-node PA6 elements, 10-nodes tetrahedron or Pentahedron 6 nodes.

4.Using /INIBRI/STRS_F, there is no density of the deformed elements.

Before the first cycle, RADIOSS will check consistency of the input stress tensor with material data (stiffness and density):

If the stress is not fulfilled, then RADIOSS will correct the diagonal entry of the stress tensor:
